[Hallb-engineering] [New Logentry] Follow-up Re: Follow-up Re: Torus strain gauge alarm again

The Sensor that was alarming was SG817D1HB3:Force (one of two load cells on the S1 DS vertical support) Alarm value was 7000lbs  it was reading ~7020lbs.  I changed its alarm point to 7500lbs.
During the original run this load cell read 6680lbs with both the Torus and Solenoid at positive current. 

When Bob and I adjusted the OOPS  on 1/8/18 we did get a small change to the vertical supports, this may have contributed to the need to reset the alarm value, or it could be caused by a drift in the force readback due to slight changes in temperature of the link and the strain gage temperature compensation.
